My 25 OH D is low but my 1,25 dihydroxy vit d is average?
I am a bit concerned because my 25 Hydroxy vitamin D is low at 60nmol/l but my 1,25 dihydroxy vit d is normal at 100 (range 60-149).
I am happy to supplement big time to get my 25
hydroxy levels way back up but it seems concerning to me that my 1,25 dihydroxy levels are normal with such a low 25 hydroxy level.
I have read that some people have low 25 hydroxy levels and very high 1,25 dihydroxy levels and this is a dangerous problem to have and sign of body illness. Should I be worried about the difference in the 2 levels that I have and concerned that taking substantial vit d supplementation will quickly drive my 1,25 way to high or am I okay?
Are my levels fairly normal in the general population or usually when someone has a low 25hydro vit d level they also have a very low 1,25dihydro vit d level?
Thanks a ton for the help and great website!!
